METHODS AND APPARATUS TO DETECT A PRESENCE OF A CONDUCTIVE OBJECT

A method and apparatus determine a plurality of regions, each of the plurality of regions having a detected change in capacitance value that meets or exceeds a threshold value. In an embodiment, the method and apparatus fit a shape to the plurality of regions and determine another region, the other...

Summary:A method and apparatus determine a plurality of regions, each of the plurality of regions having a detected change in capacitance value that meets or exceeds a threshold value. In an embodiment, the method and apparatus fit a shape to the plurality of regions and determine another region, the other region being within the fitted shape and not having the detected change in capacitance value that meets or exceeds the threshold value. The method and apparatus may assign an assigned change in capacitance value to the other region.
